Diodes has released a non-isolated 10W power supply IC that delivers up to 10W or 600mA from universal mains. It has an internal 700V mosfet and works with mains from 85Vac to 300Vac, and typically with peak current up to 1.1A. “A key differentiator of this switcher IC is that it supports conventional off-line non-isolated ...

Anritsu has created the MS27201A remote spectrum monitor series, that includes a 43.5GHz version for new satellite downlink bands. A 110MHz measurement bandwidth supports common satellite downlink spans, DANL (displayed average noise level) is -164dBm and the typical TOI (third-order intercept point) is +20dBm. Other MS27201A versions work up to 9GHz or 20GHz. All work down ...

NXP has combined NFC, secure authentication, anti-tamper and a sensor interface into a single battery-free chip family called NTAG 22x. The parts are aimed high-volume tagging applications, for example: authenticating retail products or protecting them from tampering, or battery-free environment sensing. They include ISO/IEC 14443-A communication and function as an NFC Forum Type 2 tag, and ...

Toshiba has announced a three-phase brushless dc motor driver with sensor-less sinewave control. The IC, called TC78B011FTG, is a ‘pre-driver’ in the company’s nomenclature because it needs six external mosfets wired as a three-phase bridge to switch motor current. Operation is from 5.5 to 27V, and the same IC can implement either closed-loop or open-loop ...

Flow batteries show promise for grid-scale storage as, like fuel cells, they decouple power output and energy storage when building a battery: the reactor is sized for power output and the surrounding tanks are sized for energy capacity. Given a low-cost working fluid and big tanks, they could store enormous amounts of energy. Seeking that ...

Wurth has written an application note about balancing series-connected supercapacitors. There are other similar resources on the web, but this one stands out as, alongside the usual resistor, Zener and op-amp circuits, it includes balancing using Advanced Linear Devices’ unusual regulating mosfets, and ADI’s LTC3128 charger and balancer that flips power from the most to the ...

Alpha and Omega Semiconductor has created a 5A electronic fuse IC for sub-power rails in servers. On-resistance is typically 20mΩ. Dubbed AOZ18101DI, they come in 3 x 3mm DFN system-in-packages containing a control IC and back-to-back trench mosfets. The internal mosfets are n-channel, biased using a built-in charge pump. “The eFuse continuously monitors the current flowing ...
